I don't understand cuz when radiation collides with atoms, it can knock electrons out of their srtucture, creating a charged particle!!so that means the charged particle has to be positive cuz the atom has lost it's electron and left with more protons!!but in the book it says the ion can be negative!!but i don't understand why??

when u say they can gain electron do u mean a Beta particle?

if in gains a electron it becomes negative.

Definition: An atom or group of atoms that carry a positive or negative electrical charge as a result of gaining or losing electrons. [See source.] This means, for ions there is an imbalance of charge between the protons in the core and the electrons in the shells. This results because in non-ionic atoms the numbers protons and electrons are always equal; so that the net charge is zero.
If an atom gains electrons, then it will be a negatively charged ion. If electrons are lost from a non ionic atom, it will be positively charged.
Collisions with photons (e.g., gamma rays) can knock electrons out of orbit. In nature, hot desert winds can also strip electrons. Both will result in positive ions.
There are a lot of ways negative ions can be formed. There are cesium negative ion sputter guns for example. [See source.] And some people claim that something as commonplace as rain can leave behind negative ions in the air.

An ion can have a negative charge or a positive charge. An atom that has lost one or more electrons will have a positive charge because it lost the negatively charged electron(s). An atom can also gain one or more extra electrons thus making the net charge negative.

When an outer electron is lost, the atom becomes a positive ion.
When it gains an electron in the outer orbit, the atom becomes a negative ion.
Beta particle is the electron coming from the inner structure of the atom.

yes when an atom gains 1 electron it becomes -ve and when it loses 1 electron it becomes +ve......
well in an ordinary atom, there are equal proton and electron numbers so that the net charge is zero
you cannot remove or add a proton in an atom, you can only add or remove an electron.... when you add 1 electron, there is 1 more electron than proton so that the net charge is -1
when you remove an electron there is 1 electron less such that there is 1 more proton than electron.... and you get a +ve atom

Yes. When a simple salt like sodium chloride dissolves in water the sodium ions and chlorine ions separate (dissociates). Sodium ions in solution are positive and Chlorine ions in solution are negative. Sodium has lost an electron to the chlorine atom. Likewise, chlorine has an taken an electron from the sodium atom.

An ion is an atom that is either positivly or negetivly charged. due to giving or gaining electrons.
take salt water... Na+ and Cl- they are both ions
yes a beta particle is an electron, and alpha is two neutrons and two protons.

Ions can be negative or positive. It's when a negative and positive ion interact that a "salt" (just like real table salt) is formed
